Guwahati/Chennai, June 23: A devastating ammonia gas leak at a seafood processing and export facility in Tamil Nadu's Tiruvallur district has resulted in the deaths of nine individuals, including two workers from Assam. This incident has reignited concerns regarding the safety and working conditions of Assamese migrant laborers employed outside their home state.

Although the identities of the deceased Assamese workers have not yet been officially released, this tragedy highlights the precarious situations faced by many migrants who leave Assam in search of better job prospects across the country.

The industrial mishap took place on June 21 at a seafood processing unit located in the Kannigaipair-Manjangaranai region near Periyapalayam, marking it as one of the most severe industrial accidents in Tamil Nadu in recent years.

Officials reported that the death toll rose to nine after one more injured worker passed away during treatment. Among the victims, seven hailed from Odisha while two were from Assam, with the majority being female migrant workers employed at the site.

According to the Tamil Nadu Health and Family Welfare Department, approximately 80 workers were impacted by the ammonia leak. While two individuals have recovered and been discharged, 69 others are still receiving treatment and medical care at various hospitals in Chennai and Tiruvallur.

The number of casualties increased steadily in the aftermath of the incident, with two workers dying on the night of the leak, June 21. By Monday evening, the toll had reached six, and three more succumbed to their injuries by Tuesday morning.

The injured workers are currently being treated at Vels Hospital, Venkateswara Hospital, Rajiv Gandhi Government General Hospital, and Government Stanley Medical College Hospital.

In response to the incident, the Tamil Nadu government has initiated a review of industrial safety protocols and emergency response strategies at the facility. A three-member committee has been formed to investigate the incident and is expected to present its interim findings to Chief Minister C. Joseph Vijay.

Authorities are still determining the precise cause of the ammonia leak.

This tragic event follows a series of incidents involving Assamese migrant workers in various states. In October 2025, nine workers from Assam lost their lives in a construction site accident at the Ennore Special Economic Zone thermal power station near Chennai, which briefly drew national attention to the dangers faced by the state's migrant workforce.

In light of the recurring fatalities of Assamese citizens outside the state, the Assam government had previously launched the Shraddhanjali scheme, aimed at assisting in the transportation of deceased individuals back home. This initiative provides logistical and financial support to families of deceased Assamese citizens who die outside the state due to accidents or other causes, ensuring they are brought back with dignity.

With this latest tragedy claiming the lives of more Assamese workers, it is likely that renewed scrutiny will arise regarding workplace safety standards, migrant welfare initiatives, and the protections available to laborers working far from their homes.
